Dock for Windows
A dock is an app bar on the edge of the screen, like the Mac's. On Windows it can live next to the taskbar or replace it. This guide explains what a dock does, what to look for and how to start.
Quick answer
A dock for Windows is an app that shows your pinned and running apps on a bar at the edge of the screen, usually with icon magnification. The main ones today are Doca (environments, widgets and the magnifier, paid with a free trial), Winstep Nexus (a veteran with a free version), MyDockFinder (macOS look, on Steam) and Seelen UI (free, a whole desktop). Compare them in the table below.
Dock or taskbar?
The Windows taskbar is a fixed strip mixing apps, search, widgets and the tray. A dock is lighter: it floats over the desktop, holds only what you chose and usually has the magnifier. You can use both together, or just the dock.
What a good Windows dock needs
- Real running apps: the dot under open apps, window previews, clicks that minimize and switch, like the taskbar.
- Work on current Windows 11: many old docks stopped at Windows 7 and break with display scaling, multiple monitors and Store apps.
- Get out of the way: in a full-screen game or video, the dock disappears, then comes back.
- Restore everything on exit: if the dock hides the taskbar, it must come back when the dock closes (even if it crashes).
- Be light: a dock stays open all day.

What Doca does differently
- Environments: one dock for each moment (Work, Study, Leisure), each with its own apps, widgets, color and windows. A spin of the mouse wheel over the dock switches.
- 40+ widgets inside the dock: clock, Pomodoro, weather, quotes, CPU, Steam, Claude Code usage. And you can build your own.
- A dock on each monitor, with the apps open on that monitor and each screen's position.
- It can replace the taskbar, with Start, the clock, status icons and the tray.
How to install without surprises
- Prefer the Microsoft Store: the app is verified and Windows shows no warning.
- Start with the dock next to the taskbar. Hide the taskbar only once you're used to it.
- Test full screen (a video, a game) and a second monitor, if you have one.
Frequently asked questions
Does Windows have a built-in dock?
No. Windows has the taskbar. Since September 2026 it can move to the top or sides, but it still has no magnification and no widgets on the bar. A dock is a separate app.
What's the best free dock for Windows?
Of those we checked, Winstep Nexus has a free version for personal use and Seelen UI is free and open source. Doca is paid (US$ 9 once) with a 7-day free trial with everything unlocked.
Does a dock slow Windows down?
A good one doesn't. Doca uses around 40 MB of memory and sits nearly idle when you're not using it.
Does the dock work with multiple monitors?
Doca puts a dock on each monitor, with the apps open on that monitor and each screen's position.
Does it work on Windows 10?
Yes, on Windows 10 (version 2004 or newer) and Windows 11, on x64 and ARM64.
